In this paper we describe a hands-on laboratory oriented instructional package that we have developed for data communications and networking. The package consists of a software tool, together with instructional material for a laboratory based networking curriculum. The software is based on a simulation environment that enables the student to experiment with various networking protocols, on an easy to use graphical user interface (GUI). Data message flows, packet losses, control/routing message flows, virtual circuit ...

Special consideration was taken concerning the cabling and the planning of the physical and logical configuration of the classroom network, due to the need to run experiments using network equipment like routers and ATM switches. An important part of the laboratories is to reinforce the concepts acquired in the theoretical lectures and, for this reason, the experiments were planned for every network layer. Most of the experiments use software tools specifically developed for the experiments, like runtime libraries and simulators. Besides, the course material profits from tools developed for web distance learning training, including multimedia, on-line evaluation tests, chats and simulators. The laboratory has been running for three years and a new revision of the classrooms and of the experiments is being implemented.
An introductory course in computer communication and networks
ACM SIGCOMM Computer Communication Review, 1992
This paper reports on the curriculum contents and experience obtained in the teaching of a semester-long introductory course in computer communication networks. The course is aimed at first year graduate and senior undergraduate students and covers a broad survey of networking issues. We focus on all seven layers of the OSI reference model and assign four major programming projects to reinforce the ideas covered in lectures. Projects include writing the client side of a client-server program that implements a sliding window data-link layer protocol complete with acknowledgements and retransmissions, writing client and server programs that interact via remote procedure calls, and writing client and server programs that use UDP datgrams to locate and register services with a name server utility and TCP to actually invoke services registered with the name server.
Undergraduate data communications and networking projects using opnet and wireshark software
ACM SIGCSE Bulletin, 2008
The national importance of creating "content reflecting cutting edge developments in STEM fields" has been recognized the National Science Foundation. The National Research Council has also noted that creating engaging laboratory and classroom experiences is a challenge to effective undergraduate education in STEM disciplines. In this paper we present our endeavors to address these issues in the field of computer networks. We discuss our experiences with novel laboratory and classroom projects using OPNET and Wireshark software products in undergraduate networking courses. These laboratories help undergraduate students understand fundamental networking concepts through modeling and simulation of computing systems. We have found that their use enhances student learning and interest in the subject of computer networks.
DEVS-Suite simulator: a tool teaching network protocols
Winter Simulation Conference, 2010
Understanding of the underlying concepts, principles, and theories of computer network can significantly benefit from simulation tools. Usage and development of simulation models for computer networks, however, can be demanding in educational settings. While a variety of open source and commercial tools are available, there remains a desire for simulators that can better support student learning and instructor teaching. In this work, the DEVS-Suite general-purpose simulator is extended to support modeling of network protocols. A model library for the OSPF protocol has been developed such that the emphasis is placed on education to capture the basic principles of network protocols using sound modeling and simulation principles instead of supporting highly detailed network protocol simulations. The use and pedagogical effectiveness of the DEVS-Suite network simulator is carried out in a classroom setting. The results of the student survey are presented and discussed.
Using computer network simulation tools as supplements to computer network curriculum
30th Annual Frontiers in Education Conference. Building on A Century of Progress in Engineering Education. Conference Proceedings (IEEE Cat. No.00CH37135), 2000
Computer network technologies have been growing explosively. Teaching computer networking principles can be enhanced using simulation through the use of interactive (not statistical based) simulation. The curriculum is based on the theory that through networking simulation programs, students are able to graphically implement the concepts learned in their coursework. With networking simulation tools, students can construct, tune, and analyze network performance while reinforcing their understanding of networking theory. Network simulation tools save money by offering the user a tool to enhance the design and integration of networks. There are many network simulation tools that allow users to model LANs, MANs, and WANs on the market. This paper describes our approach to develop computer network laboratory that enhances the understanding of a computer network course. Different computer network simulation tools have been considered and COMNET III has been selected as the tool of choice. Five labs have been developed. COMNET III is a network simulation tool that allows students and networking professionals to model, tune, and analyze the performance of various types of networks. It fosters what COMNET refers to as a "building-block approach" by utilizing a GUI interface that is comprised of "blocks" or objects representing many of the objects used in real networks. The user has the ability to adjust the objects' parameters using either default, constant, or algebraic values to better model the objects' functions

We propose to develop a laboratory oriented hands-on curriculum for data communications and computer networking. This will enable students to to experiment with various networking and communications/telecommunications concepts using a workstation, a PC, or a network of workstations. They will be able to design new protocols, verify them using protocol engineering tools, implement them, and visually see the impact of their actions.
